The AFE7070/1 AFEs integrate a dual 14-bit, 65-Msamples/s DAC, programmable low-pass filter, and RF IQ modulator with an RF output range of 100 to 2,700 MHz in a 7 x 7-mm QFN package. The AFE7071 is basically a complete radio transmitter that is claimed to reduce board space by up to 80% compared to discrete implementations. It integrates a dual DAC, tunable baseband filters, IQ modulator and digital quadrature modulation correction circuit.

The AFE7070 adds a direct digital synthesizer (DDS) with 32-bit numerically controlled oscillator (NCO) and LVDS output buffer. Additional features for both parts include an adjacent channel power ratio of 66 dB with 5-MHz WCDMA and 61 dB with 20-MHz LTE at 2.1 GHz while using only 325 mW — claimed more than 50% lower than discrete designs. RF power is 0.3 dBm and output noise floor is 156 dBm/Hz.

The AFE7070EVM and AFE7071EVM are also available and include the CDCM7005 clock jitter cleaner, as well as TI power management devices, such as DC/DC converters and low-noise LDOs, to provide a complete bits-to-RF prototyping and reference design.(ea/1,000, AFE7071 $11.90, AFE7070 $23.75 — available now)
